He,

the

Columbus

of

the

East,

was

an

amazing

man.

He

was

born

in

1371

and

11

years

later,

was

caught

by

the

army

of

a

rich

young

man

called

Zhu

Di

and

made

to

work

for

him.

Over

time

the

rich

man

saw

tha

Zheng

HE

was

very

clever

and

strong

and

they

became

close

friends.

In

1403

Zhu

Di

was

made

the

King

of

China

and

he

asked

Zheng

He

to

join

his

new

government.

The

king

wanted

to

learn

more

about

the

world

and

show

other

countries

his

power.

He

led

many

new

ships

to

be

built

and

made

Zheng

He

their

leader.

Between

1405

and

1433,

Zheng

He

led

seven

sea

trips

to

different

parts

of

the

world.

He

certainly

travelled

to

India,

Africa

and

the

Middle

East.

A

few

people

think

his

ships

may

have

even

reached

south

America

and

Australia.

Each

trip

lasted

between

two

and

four

years

and

it

is

believed

he

sailed

more

than

50,000

kilometrs

during

the

years

of

his

travels.

With

28,000

men

and

over

300

ships,

such

as

boats

for

food,

water

and

even

soldiers’

horses,

Zheng

He

led

a

fleer（艦隊）whose

size

would

not

be

equaled

by

Europeans’

for

over

500

years

later.

On

these

trips

he

brought

with

him

many

Chinese

goods

like

silk

and

medicine

to

give

to

foreign

kings

or

to

sell

for

local

goods.

He

returned

from

each

trip

with

boats

filled

with

expensive

things

such

as

gold

and

jewellery,

foreign

guests

and

strange

animals

like

a

giraffe.

It

is

a

pity

that

we

may

never

learn

everything

about

Zheng

He’s

travels.

After

he

died

in

1433,

the

new

king,

who

believed

these

trips

were

unlucky

and

too

expensive,

had

them

stop

and

he

burned

almost

all

the

books

about

Zheng

He’s

travels.

It

is

only

in

the

last

50years

that

historians

have

begun

to

carefully

study

the

adventures

of

the

great

Zheng

when,

while

和

as

引導時間狀語從句的用法

（一）、when

的用法

如果只從現(xiàn)象來看，when

從句用的最多的是一般過去時，而主句的時態(tài)沒有限制,根據(jù)具體情況而定。

1.

When

she

came

into

my

room,

I

was

just

reading

a

book.

她走進我房間時，我正在看書。

2.

He

was

on

the

point

of

leaving

when

someone

knocked

at

the

door.

他正要走，這時有人敲門。

根據(jù)以上的例句，我們可以總結(jié)出一點：when

從句的A事件，相當于另一個事件B發(fā)生的時間點。也就是說，when

從句的重點不在動作本身發(fā)生的狀態(tài)，而只是把它作為一個時間點，所以when

多數(shù)情況下用的是一般過去時，則不用正在進行時。因為如果用正在進行時，它表示的就是一段時間而不是一個時間點了。根據(jù)這一點，有的文章補充說：when

從句的動詞大多是瞬時動詞。這種說法也可以參照。

實際上，when

從句也可以有其它的時態(tài)，但幾乎也不用進行時，因為它也只是作為一個時間參照點。例如：

When

I

got

to

the

airport,

the

guests

had

left.

當我趕到飛機場時，客人們已經(jīng)離開了。

2.

When

he

had

finished

his

homework,

he

took

a

short

rest.

當他完成作業(yè)后,他休息了一會兒。

(二)、while

的用法

相比于when

來說，while

從句的側(cè)重點就不一樣了。while

從句的側(cè)重點在于描述動作正在發(fā)生的狀態(tài)，它的意思是：當while

事件正在發(fā)生的時候，另一件事如何如何。所以，while

從句一般用的是正在進行時。而另一件事的狀態(tài)沒有硬性的要求，根據(jù)具體情況而定。例如：

1.

While

my

wife

was

reading

the

newspaper,

I

was

watching

TV.

當妻子正在看報紙的時候，我正在看電視。

2.

While

they

were

talking,

the

bell

rang.

正在他們談話的時候，上課鈴響了。從時間的角度來看，while表示的是一段時間，是一個過程。這是while的側(cè)重點。因此，如果含有“一段時間”的含義的時候，就可以用while。3.Strikewhiletheironishot.趁熱打鐵。這句話中，是說趁著鐵是熱的這段時間，趕緊打鐵。如果換成when意思就變了，相當于說鐵只熱了一下，打一下，然后鐵就冷了。這顯然不符合文意。（三）、as

的用法

as

從句表示的也是一件事情正在發(fā)生，另一件事也正在進行當中。但與

while

從句不同的是，as

從句用的一般不用正在進行時，而只是一般過去時。as

從句一般可以翻譯成“邊……邊……”。例如：

1.

As

my

mother

sang

those

old

songs,

tears

ran

down

her

cheeks.

當我媽媽唱起那些老歌時，眼淚順著她的臉頰流了下來。

2.

The

students

took

notes

as

they

listened.

學生們邊聽課邊做筆記。

as

表達的事件，往往只是主句動作發(fā)生的背景或條件時，as

只是一個次要的時間說明，不像while

從句有強調(diào)

while

動作本身的意思。因此，as

常常翻譯成“隨著……”之意。例如：

As

the

time

went

on，the

weather

got

worse.

隨著時間的推移，氣候更加糟糕。

2.

The

atmosphere

gets

thinner

and

thinner

as

the

height

increases.

隨著高度的增加，大氣越來越稀薄。少數(shù)情況下，如果強調(diào)動作正在發(fā)生，as

從句也可以用正在進行時。這只能算是特例了。

The

sad

mother

sat

on

the

roadside,

shouting

as

she

was

crying.

傷心的媽媽坐在路邊，邊哭邊叫喊。

2.

As

we

were

going

out,

it

began

to

snow.

正當我們出門時，雪開始下起來。（四）、when,

while,

as

的互換

如果從句動作和主句動作同時發(fā)生，并且從句動作為延續(xù)性動詞時，when，while，as

可以互換使用。

1.

When

/While

/As

we

were

dancing,

a

stranger

came

in.

當我們跳舞時，一位陌生人走了進來。

[dance

為延續(xù)性動詞]

2.

When

/While

/As

she

was

making

a

phone

call,

I

was

writing

a

letter.

比較while,when,asas,when引導短暫性動作的動詞。例如：Justas/Justwhen/WhenIstoppedmycar,amancameuptome.我剎車后，有一個人向我走來。當從句的動作發(fā)生于主句動作之前，只能用when引導這個從句，不可用as或while。例如：Whenyouhavefinishedyourwork,youmayhavearest.干完活后，你可以休息一下。從句表示“隨時間推移”連詞能用as，不用when或while。例如：Asthedaywenton,theweathergotworse.日子一天天過去，天氣越變越壞。擴充知識點：

It

is

since從以來多長時間了(因為since

+從句或名詞，表示一段時間)

It

is

five

years

since

we

met

last

time.從我們上次見面已經(jīng)五年了。

It

is

+before，(才)

It

was

a

long

time

before

I

went

to

sleep

again.

過了很長時間我才睡著。

It

was

an

hour

before(＝until)

the

police

arrived.

過了一個小時，警察才來。

2.由as

soon

as,

immediately,

directly,

instantly,

the

moment,

the

instant,

the

minute,

等引導的時間狀語從句。

這些連詞都表示“一就”。例如：

I

will

go

there

directly

I

have

finished

my

breakfast.

吃完早飯，我立即到那里去。

The

moment

I

heard

the

news,

I

hastened

to

the

spot.我一聽到消息，馬上趕到了出事地點。

3.由by

the

time引導的時間狀語從句。

注意時態(tài)的變化：在一般情況下，如果從句的謂語動詞用一般過去時，主句的謂語動詞用過去完成時；如果主句的謂語動詞用一般現(xiàn)在時，主句的謂語動詞用將來完成時。例如：

By

the

time

you

came

back,

I

had

finished

this

book.到你回來時，我已經(jīng)寫完這本書了。

By

the

time

you

come

here

tomorrow,

I

will

have

finished

this

work.

你明天來這兒的時候，我將已經(jīng)完成此工作了。

注意：when

while

as

after

before

as

soon

as

since

till

/until

by

the

time

在時間狀語從句中，要注意時態(tài)一致。一般情況下主句是將來時的時候，從句要用一般現(xiàn)在時。
